The Anthropocene hypothesis regards humanity as a geological force, its activities effectively altering the earth system's metabolic structures: sediments, currents, and rays are redistributed towards unknown configurations. The publication Textures of the Anthropocene: Grain Vapor Ray engages with earthly conditions and human imagination in a discursive, trans-historical experiment. Departing from a corpus of historical documents spanning several centuries, scholars, theorists, scientists, and artists have been asked to grapple with the constantly shifting qualities of the particular, fleeting, and energetic, presenting new positions on the textures and forms that knowledge takes on within the Anthropocene.
